Review request for Plasma and Alessandro Diaferia.


Changes
-------

- I fixed the bug that caused some applets to disappear on resize
- I created 3 functions in playbackcontrol.h and controller.h that allow the states to give slider and playback button pointers to the controller. The connections between these widgets and the player are handled by the states. I could have done it the other way round (the controller gives pointers to the states) but this way is more consistent with the rest of the way the states work and also makes the layout of widgtes in the controller easier. I will have a closer look whether I can take further things out of the controller but I first wanted some feedback from this patch.

P.S. Transforming git diffs into reviewboard patches was not easy but I found a script that helped. Puuh 


Summary
-------

The state calsses now have less functions. Only one for connections and one for configuration. The first one is only called once at PMC initialization, the second one is called at each state switch. Some connections can conflict between states. Those are connected at entry() and disconnected at exit(). Thanks to Alessandr's work we can now also configure the layout from within the state class (I only had to correct some namespace stuff in the medialayout class, I hope that was correct).
This patch also gets basic functionality back. The modes are not really useful yet. Video mode is the most complete and can be used to view everything at th moment.
Next step: Clean this up a bit
Think about subclassing plasma widgets to get the widget type into the widget. This is necessary to be able to tell the controller to layout into zones.
Start work on information bar.

Testing
-------

Lots and lots. Seems to be quite slow, but I think that is a problem in the player. It always iterates over all the queue even if it should only show a picture.


Thanks,

Christophe
